Ive seen this question thrown around a little bit, first can i put headers on my 2008 ls with SAI, secondly how much horse would i be looking at if i had the short ram intake, dc sports exhaust,header,2.4 mani,comp cams,ferrera valves, the weisco pistons(alot of stuff on ttr )) and a trifecta tune with maybe a jet chip please dont make fun of me or flame but suggestions are appreciated. The only forced induction i would intend on using is n2o but thank you for your answers

im about 95% postive that installing a header with the SAI is'nt a problem lol. and from what i have heard, a fully bolted 2.2 (u basically are) along with a tune, should be good for the 170 whp range. dont quote me on it cuz im not positve, im just throwing out a somewhat educated answer.

if ur going to take the motor apart, u mise well add a cam also

DO NOT use jet chip, there aweful. Also I believe you can use any manifold (Not Header) as long as you have the trifecta tunning because i believe they can delete the SIR in your ECU. 150-170whp..really depends on dyno, tune and other factors.

Also FYI N2O is NOT forced induction. Forced induction is a supercharger or turbo...

wow i missed that part about the jet chip, just stay away from it. it doesnt help our cars at all, and im some cases, i have heard that it actually hurts it. just stick with the bolts on and a the few internal mods you have done along with the tune and ur golden. if u decide u wanna add a little juice, go for it, just make sure u get the car retuned from trifecta after you add it.

well iam assuming that after all that is said is done I will definatley feel a diffrence from all that I have of now is my short ram intake installed(k and N) and my strut bar which does nothing lol i was hoping to hid mid 14's in a 1/4 with all of that and maybe a nice shot of juice

jschatte

Didn't halfcent do a full build on his 2.2 and not get that great of numbers afterwards?

StrongIslandBalter

idk but if you wouldnt mind I would highly appreciate if you could direct me to his name so i can see what he did and got wow my english is not here today and im in class lol

nvm found him he has a pic of a turbo though

copson20

i beat 2.4 hands down. so what ever there horsepower is mine is a little more

ls1fbody

you will not break into the 14's without juice. sorry man, it just isn't going to happen. now with a 75 shot, you might.

Sentry

With everything he listed, especially with the cams, it's possible.

There's some guy on here that runs a 15 without cams.

Agreed, there are people that could do it without nitrous, super or turbo. No one has the driver mod or track to do it.

ls1fbody

i know they're capable, but even with cams, if it's a stock head, you won't gain the kind of power needed to drop a second off the 1/4 time.

i run mid 15's im going to try ad get into the 14's idc if ts a 14.99 lol...but thats not till later next year...and im doin it all n/a no engine work, all bolt ons...well maybe a port and polished head

Sentry

He doesn't need to drop a second, he needs to drop like maybe .1-.2 seconds on a good track.

Nobody has done it before, but I might just have to make it my goal for the future.

Halfcent

Yes, you can install the header, but you will need to get a reflash of your ECM to delete the software of the SAI system. Read the Sticky thread in this section to learn about it.

Valves will do nothing for power. They just allow your engine to handle more power at higher RPM.

Pistons will do nothing for power unless you are changing the compression ratio.

Stay away from anything that has the word "chip" in it. Garbage.

The rest of that stuff is fine.

Preston

75 shot with intake and exhaust will get you 14's..im in that range

isnt there a sedan in the 13's with a 75 shot

Preston

with a header downpipe exhaust intake and 2.4 mani

ls1fbody

i wasn't saying he couldn't make it into the 14's, and i agreed, a 75 shot with full bolts-ons could. i'm not trying to start a feud on 2.2 vs. 2.0, just sharing my experience.

also, switching from a SRI, to a CAI, would be a good start if you're planning on running nitrous. the colder that air is, the better.

Sentry

I want to throw on an exhaust and a 75 shot so bad. If I thought I could be in the 13's it would be tempting.

But I can't justify spending a grand in a full exhaust system when I'm just going to buy a 3" when I get my turbo. Maybe I'll go ahead and get the 3" now and just hobble until I go turbo, .

Preston

i was just throwing it out there. That he could with intake exhaust and a 75 shot, hell maybe even a 50. But ehh idk

idk he pm'd me and asked me what to do to get 14's...i told him. ha

tho he coulda read the thread. ahh wel
